Auto merge of #145343 - Kobzol:dogfood-z-no-embed-metadata, r=bjorn3

Dogfood `-Zno-embed-metadata` in the standard library

This PR dogfoods the [`-Zno-embed-metadata`](https://github.com/rust-lang/cargo/issues/15495) flag in the standard library. This removes the .rmeta portion out of the `libstd.so` file, thus reducing its filesize on disk. Notably, this reduces the amount of MiB that we ship to people who download the standard library.

I think that the only way to find out what this breaks is to try to run full CI, and then try to land it on nightly :)

rust-analyzer is a language server that provides IDE functionality for writing Rust programs. You can use it with any editor that supports the Language Server Protocol (VS Code, Vim, Emacs, Zed, etc).

rust-analyzer features include go-to-definition, find-all-references, refactorings and code completion. rust-analyzer also supports integrated formatting (with rustfmt) and integrated diagnostics (with rustc and clippy).

Internally, rust-analyzer is structured as a set of libraries for analyzing Rust code. See Architecture in the manual.
